Two DRS zones will be in place at this weekend's Bahrain Grand Prix for the first time in its history, with governing body the FIA choosing to add to the pit-straight area.

The first detection point has been placed at Turn 9, before the activation mark on the exit of Turn 10. The second detection line comes under braking for the penultimate corner, Turn 14, with the activation area situated shortly before the start-finish line.

As per the regulations, DRS can be used in the allocated zones during practice and qualifying, while in the race a driver must be within one second of a car ahead.via GP Update
